Yes every single on of your workunits is giving nothing but errors and not validating! Try upgrading to version 7.0.27 or stop using the app_info.xml file for a few units and see if that is the problem.

Are you eventually still using the old optimized apps? Something like v0.2x or v0.1x or in general anything below v0.8x? If yes, than delete them together with the app_info file. Actually, since you are using only your CPU for Milkyway, delete the app_info anyway, there's no need for it on CPU-only hosts. The current application versions you can see on the applications page, once you have deleted the app_info, BOINC will download the one you need.

As to BOINC version, I'm not sure I'd recommend v7, more something like 6.12.34, but for CPU-only crunching your 6.10.17 should be OK, I use 6.10.18 on my CPU-only hosts without any issues.

You're using a very ancient version which won't work. You can't use the old applications that are floating around the internet
